[0025] By adopting the above technical solution, the slide plate 11 divides the U-shaped frame 6 into a columnar clamping cavity and a block clamping cavity, which are respectively used to clamp cylindrical parts and block parts. By rotating the screw 10, the slider 8 is driven to move along the slide groove 7, and then the slide plate 11 is driven to move left and right, so that the V-shaped clamping groove 13 can be used to stably clamp the cylindrical parts or the clamping assembly can be used to adaptively clamp block parts of different sizes.

[0027] By adopting the above technical solution, the moving block 17 is driven to move relatively by rotating the drawing rod 16, so that the clamping jaws 18 clamp or release the block parts, thereby realizing adaptive clamping of block parts of different sizes.

[0028] This embodiment is further configured such that the angle adjustment assembly includes a transmission box 19 arranged on the outer wall of the support plate 4 on one side, one end of the rotating shaft 5 on one side penetrates the support plate 4 and extends into the transmission box 19, and a worm gear 20 is fixedly installed thereon, and a worm 21 meshing with the worm gear 20 is rotatably installed in the transmission box 19.

[0029] By adopting the above technical solution, the worm 21 is rotated to drive the worm wheel 20 and the rotating shaft 5 fixedly connected thereto to rotate, thereby adjusting the angle of the U-shaped frame 6, so that the clamp can conveniently change the clamping angle.

After releasing the handle 24, the positioning rod 22 is inserted into the new positioning hole 23 under the action of the spring 25, thereby realizing the rapid adjustment of the overall height of the slide 3 and the U-shaped frame 6.

[0032] The present embodiment is further configured such that a hand wheel is installed at one end of the screw rod 10 , the drawing rod 16 and the worm 21 .

[0033] By adopting the above technical solution, a hand wheel is provided to facilitate the operator to conveniently control the screw 10, the drawing rod 16 and the worm 21, thereby improving the operating convenience and work efficiency of the clamp.

[0034] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process.

[0035] Example:

[0036] For clamping cylindrical parts;

[0037] Part positioning: First, place the cylindrical part to be processed in the columnar clamping cavity in the U-shaped frame 6, ensuring that the center line of the part is aligned with the V-shaped clamping groove 13 to ensure the stability of the clamping.

[0038] Clamping operation: The operator holds the screw 10 and rotates the hand wheel, and the screw 10 rotates accordingly. Since the screw 10 and the slider 8 are spirally connected, rotating the screw 10 will push the slider 8 to slide to the left along the slide groove 7. The slide plate 11 fixed on the slider 8 moves synchronously, so that the V-shaped clamping groove 13 applies clamping force to the cylindrical part. Continue to rotate the screw 10 hand wheel until the V-shaped clamping groove 13 firmly clamps the cylindrical part without obvious shaking.

[0039] For clamping block parts;

[0040] Part positioning: Place the block-shaped part to be processed into the block-shaped clamping cavity, and try to make it parallel to the clamping plate 14 to facilitate uniform clamping by the clamping claws 18.

[0041] Clamping operation: the operator holds the screw 10 and rotates the handwheel, and the screw 10 rotates accordingly. Since the screw 10 and the slider 8 are spirally connected, rotating the screw 10 will push the slider 8 to slide to the right along the slide groove 7, so that a pair of clamps 14 pre-fix the parts, and then turn the handwheel of the drawing rod 16. Since the moving block 17 on the drawing rod 16 is slidingly connected to the mounting groove 15, and the side wall of the moving block 17 is provided with a clamping claw 18, the rotation of the drawing rod 16 will drive the two moving blocks 17 to move toward each other through the screw thread, and the clamping claw 18 gradually approaches and contacts the block-shaped part. Continue to rotate the handwheel until the clamping claw 18 firmly clamps the block-shaped part without obvious shaking. According to the shape and size of the block-shaped part, the position of the clamping claw 18 can be appropriately adjusted to ensure that the clamping is firm and will not cause damage to the part.

[0042] Adjust the clamping angle;

[0043] Angle preset: Predetermine the required clamping angle according to the processing requirements or workpiece characteristics. You can refer to the machine tool or process drawings, or use tools such as protractors for on-site measurements.

[0044] Angle adjustment: The operator holds the hand wheel of the worm 21 and rotates the worm 21. Since the worm 21 is meshed with the worm wheel 20, and the worm wheel 20 is fixedly connected to the rotating shaft 5, the rotation of the worm 21 will drive the worm wheel 20 and the rotating shaft 5 to rotate together. The rotation of the rotating shaft 5 will drive the U-shaped frame 6 to rotate as a whole through the support plate 4, so as to adjust the angle of the clamped parts.

[0045] Adjust the height of the fixture;

[0046] Height preselection: Determine the required working height of the fixture based on factors such as the height of the machine tool worktable and the motion range of the machining tool.

[0047] Height adjustment: The operator holds the handle 24 of the positioning rod 22 and pulls the positioning rod 22 outward to disengage it from the current positioning hole 23. Then, the slide 3 is moved up and down along the vertical plate 2 to the pre-selected height, ensuring that the positioning rods 22 on both sides of the slide 3 are aligned with the positioning holes 23 of the corresponding height. The handle 24 of the positioning rod 22 is released, and the force of the spring 25 causes the positioning rod 22 to automatically insert into the newly selected positioning hole 23, thereby completing the adjustment of the overall height of the slide 3 and the U-shaped frame 6.

[0048] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions.
